126 MR HARVEY on a Remarkable Case of Magnetic Intensity. 



time, any magnetic qualities it might possess to the balance, and 

 thus to restore to it that power of derangement which had been 

 previously removed. Suppose, for example, that the balance of 

 the first Chronometer alluded to in this paper were to have its 

 magnetism removed by the ingenious method recommended by 

 Captain SCORESBY, or by any other, is it not probable that the 

 same property would be again acquired, from the active magne- 

 tism possessed by the numerous screws, the arbor of the fusee, the 

 chain, &c. in consequence of the balance either remaining quies- 

 cent, or incessantly performing its vibrations in the neighbour- 

 hood of that which may, without impropriety, be denominated a 

 System of Magnets ? On the whole, therefore, the employment 

 of a substance in the construction of the balance, not only with- 

 out magnetism, but without the capabili ty of acquiring it, will be 

 the only effectual and perfect remedy for the anomaly in ques- 

 tion. Platina, or an alloy of platina, has been mentioned by the 

 intelligent and active philosopher last alluded to ; and it is not 

 improbable, but that it may be ultimately found as well adapted 

 to the purposes of compensation as steel. Similar precautions 

 are necessary in the formation of the balance-spring. Gold, it is 

 said, is very well adapted for this purpose.
